Was George Carlin a man of common sense or an idiot?

George Carlin was a great comedian. He was also very offensive and I have noticed that he occasionally said things that made no sense at all. His material included touchy things like politics, religion. Children, etc. What is you opinion about him? I am going to say he was both. He had alot of common sense but he also said some things that seem to me to be quite moronic. He did offend me alot of times but then again he offended everyone and everyone was a target. What is you opinion about George Carlin.
